A Forward-Looking Network: Huge Investment Connecting Türkiye to European Rail Systems
Halkalı-Kapıkule Railway Project stands out as a comprehensive investment that raises the bar in Türkiye’s logistics and passenger transportation and builds a railway network at European standards. The project, which started in 2019, is led by the Ministry of Transport and Infrastructure and is designed to strengthen the country’s cross-border trade. In this article, the technical details of the project, milestones, critical points regarding tunnel engineering and the expected dramatic improvements in travel times will be discussed.
Anatomy of Intercountry Connectivity: Three Main Axes and Strategic Challenges
Rising on a total network of 229 kilometers, the project is being implemented in three main stages. Each stage has its own challenges and values. Kapıkule-Çerkezköy (153 km) section has been completed and is being prepared for opening; Intensive work continues in the field in the Çerkezköy-Ispartakule (67 km) section; Ispartakule-Halkalı (8.4 km) stands out as a critical cornerstone regarding the lake crossing. This section aims to ensure that the railway operates without interruption, especially thanks to the tunnels under Küçükçekmece Lake.
Strong Engineering: The Depth and Importance of Küçükçekmece Lake Passage
Küçükçekmece Lake crossing, one of the most critical engineering marvels of the project, is located in the 8.4-kilometer Ispartakule-Halkalı stage. Two tube tunnels passing through the narrow point of the lake were designed to ensure uninterrupted operation of the railway even during flooding, seismic effects or planned maintenance. These tunnels, visible even in drone images, show how advanced the infrastructure has been planned. The construction of tunnels attracts attention with special engineering solutions that can balance ground conditions and water pressure. This chapter details the technical details of construction, materials required, and safety standards.
Three Stages, One Purpose: A Railway Network at European Standards
The main goal of the project is to provide a rapid transition to a railway network of European standards and to bring Türkiye noticeably closer to Europe. Kapıkule-Çerkezköy line is of critical importance for freight transportation; This stage will revitalize regional trade by making rail transportation much more efficient than road transportation. In the Çerkezköy-Ispartakule section, infrastructure modernization, signaling and energy investments are brought together. In the Ispartakule-Halkalı section, conventional passenger logistics integrated with the lake crossing and high-speed train compatible rails are targeted. This triple approach brings the trio of time savings, security and capacity increase at the same time.
Clear Improvements in Expected Travel Times
When the project is completed, the travel time between Istanbul and Kapıkule is expected to decrease from 4 hours to 1.5 hours. A similar efficiency increase is also expected in freight transportation; The 8.5-hour journey for freight trains will be reduced to approximately 3.5 hours. This is considered a critical step not only in terms of saving time, but also in terms of increasing the speed of international trade by reducing costs. The project will strengthen the Europe-East corridor and reinforce Türkiye’s integration with export markets.
A New Balance in the Passenger Network: Qualified Comfort and Capacity Increase
On the passenger transportation side, high comfort standards, safety measures and the total capacity of the line not only reduce travel times; It also facilitates tourist flow and business travel. Modern stations create long-term social benefits for citizens thanks to accessibility-oriented designs and integrations. Digitalization in signaling and control centers increases train frequencies and guarantees uninterrupted service delivery along the line.
Environmental and Sustainability Dimension
Environmental sustainability is also a critical focus in the project. Multi-layered environmental impact analyzes (EAA) and monitoring mechanisms are applied in order to minimize environmental impacts, especially in the lake transition region, without damaging the aquatic ecosystem. The recycling potential and energy efficiency of the materials used during the construction phase are aligned with the long-term sustainability goals of the project. In addition, electrification and energy management solutions have been implemented to increase the energy efficiency of the railway infrastructure.
Economic Potential: Regional and International Impacts
From the broadest perspective, the Halkalı-Kapıkule line is not only a connection within Türkiye, but also a bridge that strengthens the trade corridor between Europe and Asia. With increasing transportation capacity, new opportunities arise for high-speed train integration and logistics centers. Employment and investment opportunities are increasing for the provinces in the region; The added value created through construction, equipment supply and technical services directly contributes to regional development. In addition, a safe and fast railway ecosystem is established thanks to high standard security protocols.
A Future-Ready Infrastructure: Commissioning and Operational Readies
The commissioning process includes detailed plans for signaling and automation systems, maintenance management and safety standards. These plans include training programs that increase the competence of the operational team in the field and intervention protocols suitable for crisis scenarios. Thanks to the integrated operation center, instant data is collected along the line and train flows and maintenance work are coordinated. Thus, the risks of interruptions along the line are minimized and a reliable travel experience is provided for passengers.
Monitoring, Reporting and Performance Indicators
The project sets clear performance indicators (KPIs) to measure its success. These include line operating time, passenger satisfaction, carrying capacity and safety incidents. In addition, environmental indicators such as energy consumption, carbon footprint and water management are closely monitored in line with sustainability targets. This approach reveals both the economic and social benefits of the project with concrete data.
Social Value: A Transportation Vision Focused on Public Service
This project is seen as a public service that increases the quality of life of the city, beyond being just an infrastructure construction. Comfortable journeys that encourage public transportation reduce urban traffic and contribute to improving air quality. New employment opportunities and training programs for citizens living in the region increase the social value of the project. In addition, thanks to the transfer of know-how in the sector, railway expertise and technical skills are strengthened throughout the country.
